Staff Sgt. Shaun Martin, a combat medic assigned to Blanchfield Army Community Hospital's LaPointe Army Medical Home on Fort Campbell, drinks from a 16-ounce bottle of water to maintain his hydration for optimal performance. On average, the Army recommends men should consume about 100 ounces of fluid (3 liters) each day, and women should aim for about 70 ounces (2 liters) for baseline hydration. In hot and humid environments and during physical activity, more is needed to maintain hydration — about one ounce per pound of body weight. To reach your goal, drink regularly and frequently, even if you are not thirsty to avoid dehydration. Water is usually the best choice over coffee, soda, energy drinks and alcohol because those beverages can pull water from the body and promote dehydration. (U.S. Army photo by Maria Yager)
